Hangzhou, ZhejiangAges 18 years+ - NCT04722341Recruiting
Time-limited eating for people with certain breast or rectal cancers
This study tests whether eating only within a shorter daily time window can improve cancer outcomes in people with specific breast or rectal cancers. It also looks at how this affects the body (such as metabolism) and who is most likely to benefit.
Birmingham, AlabamaAges 18 years+ - NCT07383441RecruitingPhase 3
Adding Biotherapy or Placebo to Standard Kidney Cancer Treatment
This trial tests whether adding a biotherapy (a special drug from a living source) or a placebo to standard treatments helps people with advanced kidney cancer. It may be a good option if your cancer hasn't been treated yet and you are in fairly good health.
Fayetteville, ArkansasAges 18 years+ - NCT06429696RecruitingPhase 2
Maintenance therapy for extensive stage small cell lung cancer
This study tests if a combination of an immunotherapy drug (PD-L1 inhibitor) and a targeted therapy pill (apatinib) can help keep extensive stage small cell lung cancer from growing after initial treatment. It is for people whose cancer was controlled with first-line chemo-immunotherapy.
Guangzhou, GuangdongAges 18–75 - NCT06347926Recruiting
Light therapy for menopause symptoms in breast cancer
This study tests a light-based treatment (photobiomodulation) to see if it improves sexual quality of life for women with breast cancer who have menopause-related vaginal symptoms that the usual moisturizers did not relieve.

Eribulin every two weeks vs standard schedule for advanced breast cancer
This trial compares a new every-two-week dosing schedule of the chemotherapy drug eribulin to the standard schedule in people with HER2-negative breast cancer that has returned or spread. The goal is to see if the biweekly regimen is safer or works better.
Beijing, BAges 18 years+ - NCT07739485RecruitingPhase 1/Phase 2
Oral paclitaxel before surgery for triple-negative breast cancer
This trial tests an oral form of a common chemo drug, paclitaxel, given before surgery for triple-negative breast cancer. It aims to find the best dose and see how well it shrinks tumors.
Guiyang, GuizhouAges 18–70 - NCT04437160RecruitingPhase 2
Chemo after surgery for triple-negative breast cancer with leftover tumor
This Phase 2 study tests chemotherapy given after surgery for people with triple-negative breast cancer who still have cancer left after initial (neoadjuvant) chemo. It may help lower the chance the cancer comes back in people at higher risk based on leftover tumor and lymph node findings.
